Arabic Surveying Project
Lesson 5 of 8
Objective: SWBAT to apply knowledge of similar triangles to a real-world survey project..
Project Set-Up and Practice
This Project will ask students to utilize properties of similar triangles to find measurements of tall objects (MP 1). Students will first set-up the project so that there are two similar triangles formed. Students should first pick a tall object to find the height (i.e. project, top of board, top of room, etc) (MP 4).
In order to complete this project, you will need the following supplies:
Meter Stick/Tape Measures
You may want to put students in groups of 3-4, and assign specific roles. For example, one student could be in charge of each material; this means, that one student woudl be in charge of the mirror, another the measurer, another the laser pointer and another the writer. Each student should take a turn though in viewing how we use the mirror to reflect the laser - it's really cool! Please also note that there are follow-up questions and a reflection in the project document. S
This project can be extended with the following at-home activity:
Create your own experiment at home or after school. Pick an object that
would be unsafe to measure on your own (i.e. top of a building, clock tower at school, tree in your yard etc.).
